ABSTRACT
During the operations phase of the incident, the Public Safety Sampling Team (PSST) will make multiple entries into the crime scene to assess and classify the threat. ¨e PSST will recover public safety samples that will be used to in an e«ort to identify the suspected agent or chemical and to mitigate the risks to the public and responders. ¨ese PSST members should follow the FBI 12-Step Crime Scene Management Process. ¨e process includes documenting the original appearance of the scene and the evidence, as well as limiting the alteration to the crime scene, evidence contamination/crosscontamination, or destruction. For these reasons it is imperative that the CBRNE CSIU be closely involved with the PSST planning and operations. Remember, these PSSTs will be conducting work that will be directly impacting the crime scene investigation.
